Stocken bei Musikausgabe über mehrere Kanäle

Hallo an alle!

Ich habe hier erfolgreich eine Multiroom-Wiregate Installation laufen mit Alsa-only.

Ich habe die bewährte 7.1 USB Soundkarte und verwende hiervon 1 Ausgang als Stereo für draußen und alle anderen (6 an der Zahl) für die verschiedenen Räume Mono. Wenn ich nun im MPdroid die 6 Mono Kanäle bei einem MPD zuschalte stockt und ruckelt es gewaltig. Umso mehr Kanäle umso schlimmer. Bei einem oder zwei Kanäle ist noch alles fein. Woran könnte das liegen? Mit den Buffern habe ich schon rumgespielt. Bringt ein wenig Besserung aber behebt das Problem nicht völlig.

Btw: Gibt es eine Möglichkeit den Kopfhörerausgang der Soundkarte noch zusätzlich zu nutzen?

Gruß Thomas

Hallo ja du musst ihn nur in der asound.conf aktivieren. Das ruckeln ist denke ich ein Problem mit dem neuen mpd da gab es früher einen älteren.
Auch hat das WG seit einigen patchleveln eine deutlich höhere one-wire last. Bei mit zumindest...

Ein Kollege hatte auch ähnliche Probleme (an rpi) mit mpd. War nicht weg zu bekommen. Damals gab ich vermutet es liegt ab den mono Kanälen. Wäre interessant ob eine zweite sound Karte in Verbindung mit alle Kanäle auf stereo Abhilfe schaffen würde...

Magst du mal Daten Posten wieviel prozessorlast in den einzelnen Zuständen gefressen wird?

Hi,

Also wenn ich alle Mono Kanäle eingeschaltet habe zeigt das Wiregate 5.98 als 1 Minute Durchschnitt an.
Heisst das nun 5%???

[henfri]

Nein. 600%
Poste mal die Ausgabe von Top.

600 % ???

Das geht ja wohl nicht. Hab ja keinen Hexacore im Wiregate :-)

Hallo

0k also entspricht die Zahl den derzeit aktiven nicht unterbrechbaren Prozessen pro CPU. Dann ist 5 also ziemlich übel. I See.

Nun ist die Load allerdings schon ohne den MPD bei 1.

Habe aber auch noch den SMA Spot laufen welcher über EIBD und UDP die Werte rausschreibt per Cronjob alle 5 Minuten sollte also nichts machen.

Und dann habe ich noch 4 EHZ Leseköpfe.

Vielleicht sollte ich doch noch nen PI dazu nehmen

[TBrueck]

So, ich habe einen Übeltäter gefunden. VZLogger!!!

Komplett entfernt sinkt die CPU-Load enorm. Liegt jetzt noch bei knapp über 1.

Werde jetzt hier wohl den SourceCode wie beim SMASpot anpassen, so dass dieser direkt die Werte auf den KNX Bus schreibt und dann per Cronjob ausführen.

Vielleicht versuche ich aber trotzdem etwas auf den PI auszulagern.

Gruß Thomas

Ist das zuckeln beim mpd dann auch weg?

[TBrueck]

Es wird besser aber ganz weg ist es nicht also wenn alle Kanäle an sind bei einer Instanz dann ruckelt es sehr.

[vlamers]

Magst du deine asound.conf und mpd.conf Posten.
Vielleicht sieht man da noch was...

Hast du schon versucht ob es was bringt wenn du in der mpd.conf ein paar Sachen ein kommentierst? Z.b das Format.
In
Und da könntest du versuchen das ganze gleich auf mono umzustellen... Evtl bringt es was.
In der asound.conf kannst du alles aus kommentieren was mit pulse zu tun hat, da du ja über alsa gehst.
8Mb buffer_size ist auch viel oder? Hab meine Werte gerade nicht im Kopf... Bin mit auch nicht sicher ob das einen negativen Einfluss haben könnte...

Und lösche doch bitte alle Kommentar Zeilen wenn du eine config postest... Macht das ganze übersichtlicher

Ich möchte an der Stelle mal einen positiven Zwischenstand abgeben, mein WG läuft jetzt seit knapp 100 Tagen (ohne Neustart) erfreulich gut mit dem Plugin und liefert fleißig Radio-Streams. Aus baulichen Gründen allerdings bisher nur in einen Raum.
Es gab seither auch keine Ausfälle, bis auf einzelne kurzzeitig nicht erreichbare Streams oder kürzlich umgestellte Stream-Urls.
Ein großes dafür an vlamers.

Vielen Dank!
Positive Rückmeldungen sind die schönsten!
